# OMERO Documentation version 5.6

The documentation for OMERO 5.6.16 is divided into three parts:

OMERO Overview and CLI User Documentation introduces the user-facing client applications and how to get started, details the CLI client, and indicates where users can access further help and support.

System Administrator Documentation includes instructions for installing and configuring an OMERO server and also information on managing users and data, a task which full system administrators can now delegate to facility managers or other trusted users using the new ‘restricted administrator’ role.

Developers can find more specific and technical information about OMERO in the Developer Documentation.
